Malaysian travellers and residents in Karo Regency have been advised to remain alert following the latest eruption of Mount Sinabung, one of Indonesia's most active volcanoes. The volcanic activity has necessitated the evacuation of thousands of residents from surrounding areas as a precautionary measure.

The eruption has had cascading effects on regional transport networks, with several flights disrupted due to ash clouds affecting visibility and air quality in the vicinity. Authorities have implemented travel restrictions and advisories for the affected zones.

The Malaysian government has recommended that nationals currently in the region monitor official updates from Indonesian authorities and maintain contact with their respective embassies or consulates. Travellers planning to visit North Sumatra are encouraged to check with airlines and local authorities before proceeding with their journeys.

Mount Sinabung, located approximately 40 kilometres from Karo's capital Kabanjahe, has demonstrated increased volcanic activity over recent years. Residents and visitors in the surrounding areas are urged to follow evacuation orders and safety protocols established by Indonesian disaster management officials to ensure their wellbeing.
